Patent CA-2254092-A1 (CA)
Title: Axle tilt control apparatus for industrial vehicles
Inventor: OGAWA TAKAKI
IPC: B60G17/005
Filed: 1998-11-13
Abstract: An axle tilt control apparatus for forklifts is disclosed.  The forklift includes a rear axle pivotally supported by a body frame and a rear axle rigidly fixed to the body frame.  A mast is supported at the front portion of the body frame to tilt forward and backward.  Forks are supported by the mast to be lifted and lowered.  The center of gravity of the forklift in the fore-and-aft direction approaches the front axle as the mast is tilted forward. Pivoting of the rear axle is restricted by the hydraulic cylinder when the height of the forks is higher than a predetermined height determination value and the weight of a load on the forks is heavier than a predetermined weight determination value to improve the vehicle's stability.  The weight determination value increases as the mast is tilted forward.  When a load on the forks is being unloaded, tilting of the rear axle is permitted regardless of the height of the forks and the weight of the load on the forks. Therefore, the rear axle is not unnecessarily locked.

Inventor: SLUIMAN HARM
IPC: G06F9/44
Filed: 1998-11-30
Abstract: A computer system having a graphical system user interface for accepting input from a user to create objects in an object-oriented computing environment. The system user interface generates an XML-compliant template file reflecting the work-flow defined by input from the user. A macro list generator displays a representation of the template file and prompts for user interface customization options based on the template file. The macro list generator generates an XML-compliant macro list file reflecting interface customization. The system has a custom interface generator to present the customized interface to the user, having prompts derived from the macro list data. The customized interface generator accepts input from the user in response to the customized interface prompts and generates an XML-compliant application file corresponding to the template file as modified to reflect responses of the user to the customized interface prompts.

Abstract: This invention relates to apparatus for holding a golf ball elevated above the grass.      Hitherto it has been preferred to stick a wooden peg in the grass and place the golf ball on top of this peg to make the first stroke of the ball on any given hole (1 to 18) on a golf course.      Furthermore, the prior art has damaged the earth where these wooden pegs are placed. Furthermore, the prior art gives the golfer no physical reference point which to line up his or her golf club face with the direction of the golf shot. Furthermore the prior act causes many wooden pegs to be broken during the tee off with the club. A tee off is the swing of a golf club by a player on the first stroke of a hole (1 to 18) on a golf course.

IPC: B29C45/00
Filed: 1996-09-24
Abstract: A method for molding short fiber/rubber composite articles having enhanced mechanical properties by aligning short reinforcing fibers during an injection molding process. The method comprises injecting a molding mixture through an injection gate arranged in a predetermined relationship to the molding cavity. The injection gate has a relatively small thickness in comparison to the thickness of the molding cavity. The fibers are associated with a first direction, generally parallel to the flow of the molding mixture as the molding mixture moves through the gate. As the molding mixture passes through the gate and into the cavity, the fiber direction is altered as the molding material fills the cavity.

Abstract: A dedicated data packet filtering processor whose only function is to filter data packets based on a list of source IP addresses stored in high-speed memory of the processor. The processor has a specialized operating system which controls the operation of the processor. The processor examines the source IP address of each received data packet to determine if the source IP  address matches one of the stored source IP addresses, and if there is a match, either discards or forwards the data packet depending on the processor configuration. The list of source IP addresses are updated by a service provider having a central administrative site. The service provider keeps these lists up to data and periodically updates the source IP addresses stored in the random access memory of the dedicated IP filtering processors.

Title: Production process for ether carboxylate salt
Inventor: ASAKAWA MIAKI
IPC: C07C51/367
Filed: 1999-05-31
Abstract: The present invention provides a production process for an ether carboxylate salt in which process the ether carboxylate salt is obtainable with a good yield, and the amount of expensive catalyst, as used, can be saved, and the recovery of the catalyst is easy. The production process for an ether carboxylate salt comprises the etherification step of reacting a hydroxyl-group-containing organic compound and a carboxyl-group-containing organic compound in an aqueous medium in the presence of a catalyst containing a rare earth element, wherein the carboxyl-group-containing organic compound is at least one compound selected from the group consisting of carboxyl-group-containing unsaturated organic compounds and carboxyl-group-containing epoxy compounds. This process is characterized in that the pH of the aqueous medium is in the range of 9~13, but not including 9, and in that the amount of the catalyst, as used, is in the range of 0.0001 ~ 0.4 mol per 1 mol of the carboxyl-group-containing organic compound. After the etherification step, the rare earth element is separated and recovered in the form of a water-insoluble salt. In the etherification step, the resultant ether compound is deposited in the course of the reaction.
